London -LRB- CNN -RRB- -- A funeral took place in London Friday for Mark Duggan , the father of four whose death after his cab was stopped by armed police led to protests that expanded into four days of rioting .

A horse-drawn cortege processed through the streets from his parents ' home in the north London neighborhood of Tottenham to the church in nearby Wood Green where the ceremony was held , with many mourners on hand .

Duggan , 29 , died on August 4 from a gunshot to the chest after a police unit that deals with gun crime stopped the cab that was carrying him .

The Independent Police Complaints Commission -LRB- IPCC -RRB- is still investigating the circumstances around his death and said Thursday that it `` is far from reaching any conclusions . ''

A peaceful protest in Tottenham two days after his death turned violent and rioting spread to other parts of London and other English cities over the following days .

Michael Jarrett , 47 , from Tottenham was among hundreds who turned out to pay their respects to Duggan and his family .

In 1985 , Jarrett 's mother , Cynthia , died after four police officers searched her home in Tottenham 's Broadwater Farm housing project . Anger over her death sparked the Broadwater Farm riots , in which a policeman died . The area 's reputation was tainted for years .

Speaking outside the church where Duggan 's funeral was held , Jarrett told CNN little had changed in the decades since then . `` The ethnic minorities are still being mistreated , '' he said . `` I do n't think a lot changed , the mood in the area is one of regret and sorrow . But there is still a lot of mistrust where the police are concerned . ''

He said politicians who blamed people who `` just want to loot , steal and riot '' for the unrest that broke out last month need to look at the underlying problems behind such behavior .

`` I actually condemn the looting and the burning of buildings , '' he said , `` but I understand the situation behind and the frustration and anger behind it . That I do understand . Fully . ''

Yvonne Collail , 47 , from Tottenham told CNN she was concerned that the recent trouble in Tottenham had made everyone less safe and meant the police would have to carry guns , which is unusual in Britain .

London 's Metropolitan Police said in a statement beforehand that a senior officer had `` met with the parents and family of Mark Duggan and discussed the policing arrangements '' for the funeral .

`` In line with the family 's wishes , the policing will reflect the family 's desire for a local , peaceful and dignified funeral , '' the statement said .

Questions remain unanswered about the circumstances of Duggan 's death . Prime Minister David Cameron said last month that Duggan had been shot by police but the IPCC has yet to reach a formal conclusion .

In a letter to the Times of London published Thursday , the IPCC said the newspaper 's headline indicating that an officer had been cleared of shooting Duggan was incorrect and `` irresponsible . ''

The IPCC said it is continuing to follow numerous leads as it investigates Duggan 's death , including examining security camera footage , conducting forensic tests and talking to witnesses .

The commission acknowledged that `` people want answers , '' but urged them `` not to rush to judgment until they see and hear the evidence for themselves . ''

A Metropolitan Police statement Thursday said : `` The firearms officer involved in the shooting of Mark Duggan is not about to return to operational firearms duties . ''

Initial reports that Duggan shot at police were ruled out by ballistic tests , which found that a bullet that lodged in one officer 's radio was of a type issued to police . The IPCC also said there had been no exchange of fire .

A handgun that was not police issue was found at the scene , the IPCC said , but there was no evidence it had been fired during the incident .
